LQCOMOTIVE.

Specification of Letters Patent.

Patented May 3d, 1911.

Application filed January 23, 1911. Serial No. 504,030.

To all whom it may concern:

Be it known that l, JOHN ALTON, a citizen of the United States, residingat Erie, in the county of Erie and State of Pennsylvania, have inventednew and useful lmprovenients in Locomotives, of which the following is aspecification.

This invention relates to locomotives and consists incertainimprovements in the construction thereof as will be hereinafter fullydescribed and pointed out in the claims.

More particularly, the invention relates to improvements in locomotivetrucks.

`he object of the invention is to so mount an engine on a gearedlocomotive truck as to conveniently apply the power'and equalize theweight.

The invention is illustrated in the accompanying drawings as Jfollows:

Figure 1 shows an elevation of a locomotive, one of the trucks being insection.'

Fig. 2 shows an elevation of a truck the bolster being removed..

l marks the locomotive boiler, 2 the fire box, and 3 the locomotiveframe. rlChese are or' any ordinary construction.

'The truck is provided with the axles 4 and 5, and the wheels 4 and 5aare arranged on these axles. The axles are journaled in the bearings iland 5b in the trame. The

Jframe is made up of the sides 6 connectedby the end pieces 7. A crankshaft 9 is journaled in the frame in the bearings 10 and is parallel tothe axles. This is arranged at one end of the frame outside of theaxles. Cranks 11 are arranged outside the frame.

The engine cylinders 12 are arranged outside the wheels and secured tothe side frames. The cross head guides 13 extend from the cylinder andare also secured t0 the frame by a part of the frame 14 extendingbetween the wheels 4a and 5a. The cross head 15 is arranged in theguides 13 and is connected with the usual piston rod 16 and with thecrank 11 by the connecting rod 17.

A gear 18 is arranged on the crank shaft. lt meshes a gear 19 on theaxle 4. rThe gear 19 meshes a gear 20 on the shaft 21. The 'shaft 21 isjournaled in the bearings on The gear meshes a gear 9,3 on the axle 5.

A bolster Q5 extends between the side pieces (i and is mounted in anydesirable manner and has the center plate 2G on which the frame center27 rests. from the boiler to the engine by a pipe 28,

Steam is vcarried this pipe .;,eing made flexible in any desired mannerand the exhaust is carried lby the pipe 29 through, the swiveled centerof the trucks to an exhaust pipe 30 for-the rear truck and to thelocomotive stack 31 for the i front truck.

My invention doesv not relate to the boiler, or particularly to themounting of the boiler, but is directed more particularly to the truck.a'

By my invention, the cylinders and crank shafts being arranged atopposite ends of the truck, long stroke cylinders may be used with longconnecting rods thus reducing the strain on these parts. At the sametime, the engine is at the outside so that it is` readily accessible tothe engineer. The

driving connections are simplified because the connected shafts areparallel. This distribution of weight and application of power is ofgreat advantage in locomotives of this type which are subjected to veryrough usage and operated on very uneven tracks.

W hat claim as new is: y

1. In a locomotive, the combination of a locomotive frame and a swiveledtruck thereon, said truck comprising two axles, wheels o1A said axles, aframe carried by said axles, a crank shaft journaled on said .frame andextending across the frame outside the axle at one end of the Jframe,cranks at the ends of .the shaft, engines mounted on the frame andoperating on the cranks, said engines comprising cylinders mounted atthe oppo- .site end ci the :trame from the shaft-and with the axes or'the cylinders alongside of and below the top. of the Wheels on theaxles, and a driving connection between the crank shaft and one of theaxles.

2. In a locomotive, the combination of a locomotive frame and a swiveledtruck there-- on, said truck comprising two axles, wheels on said axles,a frame carried by said axles, a crank shaft journaled on said frame andextending across the frame Outside the axle at one end of the frame,cranks at the ends of the shaft, engines mounted on the frame andoperating on the cranks, said engines comprising cylinders mounted theopposite and one of the axles, and a driving connection between saidaxles.

3. In a locomotive, the combination of a locomotive frame and a swiveledtruck thereon, said truck comprising two axles, wheels on said axles, aframe carried by said axles, a crank shaft journaled on said frame andparallel to the axle, and extending across the frame outside the axle atone end of thev frame, cranks at the ends of the shaft, engines mountedon the frame and operating on the cranks, said engines comprisincylinders mounted at the opposite end o the frame from 'the shaft andwith the axes of the cylinders alongside of and below the top of thewheels on the axles, and a gear connection between the crank shaft andone of frame from the shaft and with the axes of Y the cylindersalongside of and below the top,

of the wheels on the axles, a gear connection between said crank shaftand Vone of the axles, and a gear connection between` said axles.

In a locomotive, the combination of a locomotive frame and a swiveledtruck thereon, said truck comprising two axles, wheels on said axles, aframe carried by said axles. a crank shaft journaled on' said frame andextending across the frame outside the axle at one end of the frame,cranks at the end of the shaft, engines mounted on the frame, andoperating on the cranks, said engines comprising cylinders mounted atthe opposite end of the frame from the shaft, said cylinders beingmounted outside of the wheels and with the axes'of the cylindersalongside of and below the tops of said wheels, and a driving connectionbetween the crank shaft and one of the axles.

(3. In a locomotive, the combination of a locomotive frame: a swiveledtruck con1- prising aframe, two axles journaled in the frame, wheels onsaid axles, a crank shaft parallel to said axles and arranged at the endof the frame, engines 4mounted on said frame outside the wheels, thecylinders of said engines being at the opposite ond of the frame fromthe crank shaft and with the axesvofthe cylinders alongside ofy andbelow the tops of said wheels, a spur gear on the crank shaft inside thewheels1 a spur gear on one of the axles meshing the gear on the crankshaft, and a driving connection between said axles'.

7. In a. locomotive, the combination of locomotive frame; a swiveledtruck compris 4 ing a frame, two axles journaled in the frame, wheels onsaid axles, a crank shaft parallel to said axles and arranged'at the endof the frame, engines mounted on said frame outside the wheels, thecylinders of said engines being at the opposite end of the frame fromthe crank shaft and with their axes alongside of and belowy the tops ofthe wheels, a spur gear on the crank shaft inside the wheels, a spurgear on one of the axles meshing the gear on the crank shaft, 'a spurgear on the second axle and an intermediate gear between the gears onthe axles.

S. In a locomotive, the combination of a locomotive boiler.; a tender;arigid frame` for supporting' the boiler and tender; a yswivel truckarranged under the boiler; a swivel truck arranged under the tender,said trucks each comprising two axles; wheels on the axles; a truckframe carried bythe axles; a' crank shaft journaled on said frame andextending across the frame outside the axle at one end of the frame;cranks at the end of the shafts; engines mounted on the frame andoperating the cranks, said engines comprising cylinders mounted .at theopposite end'of the frame from the shaft and having their axes alongsideof and below the wheels; and a drive connection between the crank shaftand one of the axles.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
